Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.01417 |
| Opus 5 | $0.00023 | $0.00709 |
| Sonnet 5 | $0.00009 | $0.00283 |
| Haiku 4.5 | $0.00005 | $0.00142 |
Grade A, and why
ecc-tools-cost-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
95% identical to ecc-tools-cost-audit — 25 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 161 lines — stays where its author put it; the contents beside it link to each section on GitHub.
ECC Tools Cost Audit
Use this skill when the user suspects the ECC Tools GitHub App is burning cost, over-creating PRs, bypassing usage limits, or routing free users into premium analysis paths.
This is a focused operator workflow for the sibling ECC-Tools repo. It is not a generic billing skill and it is not a repo-wide code review pass.
Skill Stack
Pull these ECC-native skills into the workflow when relevant:
autonomous-loopsfor bounded multi-step audits that cross webhooks, queues, billing, and retriesagentic-engineeringfor tracing the request path into discrete, provable unitscustomer-billing-opswhen repo behavior and customer-impact math must be separated cleanlysearch-firstbefore inventing helpers or re-implementing repo-local utilitiessecurity-reviewwhen auth, usage gates, entitlements, or secrets are touchedverification-loopfor proving rerun safety and exact post-fix statetdd-workflowwhen the fix needs regression coverage in the worker, router, or billing paths
When To Use
- user says ECC Tools burn rate, PR recursion, over-created PRs, usage-limit bypass, or premium-model leakage
- the task is in the sibling
ECC-Toolsrepo and depends on webhook handlers, queue workers, usage reservation, PR creation logic, or paid-gate enforcement - a customer report says the app created too many PRs, billed incorrectly, or analyzed code without producing a usable result
Scope Guardrails
- work in the sibling
ECC-Toolsrepo, not ineverything-claude-code - start read-only unless the user clearly asked for a fix
- do not mutate unrelated billing, checkout, or UI flows while tracing analysis burn
- treat app-generated branches and app-generated PRs as red-flag recursion paths until proved otherwise
- separate three things explicitly:
- repo-side burn root cause
- customer-facing billing impact
- product or entitlement gaps that need backlog follow-up
Workflow
1. Freeze repo scope
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ecc-tools-cost-audit is a skill published in the GitHub repository JunMystery/Agent-Guidance-Python (2 stars, last pushed 1mo ago), licensed MIT. It adds 45 tokens to every session and 1,417 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 95% identical to ecc-tools-cost-audit, differing in 25 lines, and is treated as a copy.
